REVOLVING SCRAPER.

SPECIFICATION forming part of Letters Patent No. 350,874, dated October12, 1886.

Application fileal December 3, 1895.

To aZZ whom it may concern:

Be it known that I, J AMES DUGAW, of Inkster, in the county of \Vayneand State of Michigan, have invented new and useful Iniprovenients inRevolving Scrapers; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements inroad-scrapers; and the invention consists in the peculiar construction,arrangement, and combinations of the various parts, all as more fullyhereinafter set forth.

Figure 1 is a perspective view of my im- Fig. 2 is a centrallongitudinal section through the same.

In the accompanying drawings, which form a part of this specification, Arepresents a suitable frame, between the free ends of the side bars ofwhich the scraper B is pivotally hung, as at a: The rear ends of theside bars 'of the scraper terminate in the sharpened projections C.

D is a catch rigidly secured to the scraper B, and is designed to engagewith the springdetent E, secured to the frame, such detent beingprovided with a hand-rod, F, by means of which the detent may readily bedisengaged 0 from the catch at will.

Serial No, 184.581. (No model.)

In practice the draft is applied to the frame A, as shown. \Vhen asufficient load has been scraped into the scraper and it has been hauledto the dump, the driver releases the spring-detent, the toe of thescraper catches in the ground, and is thereby turned half over,depositing its load, and, the projections C then eatehinginthe ground,the scraper is compelled to turn over into its original position, thecatch engaging with the spring-dc tent automatically. The catch 1) isrigidly secured to the back and bottom of the scraper, and serves tostiffen and strengthen the same.

That I claim as my invention is- The combination, with the frame A, ofthe scraper B, pivoted therein, the rear ends of the side bars of saidscraper terminating in sharpened projections C, the catch D, rigidlysecured to the back and bottom of said scraper, and the spring-detent1G, secured to the handle of said frame and provided with the rod F, allconstructed, arranged, and operating substantially as and for thepurpose specified;
